Notes

so they go. sensei stays on standby in case he needs to make a daring rescue (they have an agreed upon checkin time) while d casey and April sneak into the sewers and then the lair. they come up in the prison and find, of all people, karai. after discerning that she's an ally, donnie frees her and tells her to escape through the sewers, but she insists on going with them because she knows the other turtles are in danger. so she leads them to stockman's lab, where they grab the urn but don't manage to stop the fly from sounding the alarm. they're forced to run out through the throne room, but they're less worried about fighting and more worried about escaping, so they manage to blast the fuck off right before shredder gets to the throne room. they escape but shredder sends henchmen after them. when they get to the shell raiser, donnie takes karai and the urn in the stealth bike and tries to escape while the shell raiser creates a distraction. the bike malfunctions and turns off the invisibility tech. tiger claw is flying around the city and spots them (and he's got a grudge against donnie now because of the jetpack thing) they gt caught, the shell raiser gets trapped, April calls donnie, and karai puts her foot down.

she escapes the bike and hops up on the rooftops and tells shredder that she'll disappear if he doesn't let the others go, that she'll find the rat and the other turtles and disappear, and is he really willing to risk that for one turtle, two humans, and a vase? so shredder lets the others go in return for karai, and donnie promises to come back for her. he escapes back to the shell raiser and they book it. they ask where karai is, donnie tells them what happened, and they kiss him to make him feel better and say they got the urn. so they go home.
